Concrete can be purchased by the cubic yard. how much will it cost to pour a circular slab 18 ft in diameter by 3 in. for a patio if the concrete costs $40.00 per cubic yard?

Thus cost of concrete to pour the circular slab is $ 94.25

Step-by-step explanation:

Given

Diameter of circular slab, d=18 ft

Thickness of slab , t= 3 inches = 0.25 ft

Rate of concrete , R = $40.00 per cubic yard

Volume of the slab ,

Now 1 cubic yard = 27 cubic feet

Therefore volume ,

=> cost of concrete ,

Thus cost of concrete to pour the circular slab is $ 94.25

x² + 11x + 18 < 0  

[-11 ± sqrt(121 - 72)]/2 = (-11 ± 7)/2  

solution: (-9, -2)
